This is still a lot of cases, because of mixin use.

I think I can come up with a better heuristic.
How bout i do a minimal symbol lookup on the address we think the
virtual function is at, and make sure it's the start of some real
function (and if you really want to go a bit further, i'll make sure
it's a function in the class, or it's base classes)

It's going to be exteremely rare that we come up with an address that
happens to match this heuristic, but isn't correct (because we'll
end up not at the start address of a function 99% of the time if we
are wrong).
